H. ZEMKE WASHING APPARATUS Filed Aug. 11, 1928 Patented Aug. 4, 1931 PATENT GFFICE HEINRICH ZEMKE, OF BERLIN, GERIv/IANY WASHING APPARATUS Application filed August 11, 1928, Serial No. 298,905, and in Germany August 17, 1927.

This invention relates to a washing apparatus with the advantage that the washing is preserved and well washed without the use of caustic solutions, bleaching means or great force for rubbing or scrubbing.

The washing apparatus consists of a washing surface which is provided with resilient suction cups. If the washing is guided over the suction cups or if the suction cups are guided over the washing, the cups suck on the washing, thereby draw the wash-lye through the sucked on part of the washing and thus successively clean ail portions of the washing coming into touch with the cups.

The most simple form of the washing apparatus is a roller, which is made of caoutchouc, rubber or similar elastic material and which is provided with thimble like depressions which form the suction cups. To increase the resiliency hollow spaces may be provided in the rubber roller under the suction cups; or the suction cups themselves made like for instance thimbles of thin rubber, and placed in. corresponding cavities of the roller, so that they freely project with a beaded border and can thereby exercise an increased suction effect. The suction cups can also be provided in the commonly used washing boards, but in this case the prejudicial undulations forming ribs can be omitted, the suction cups being simply mounted on the smooth surface of the washing board. In order to raise the suction effect wart like elevations may be provided on the surface next to the suction cups.

The drawings show by way of example several embodiments of the invention in Fig. 1 in side View a washing apparatus consisting of two rubber rollers provided with suction cups,

Fig. 8 in cross-section a roller provided with free suction cups inserted into cavities in the roller, and

Fig. 4 shows the washing apparatus according to Fig. l with the roller construction illustrated in Fig. 3.

The washing apparatus consists for instance of a plate 1 serving as a handle, to both ends of which are fastened side plates 2. The two side plates are provided in their centre with an inwardly bent part 3 so that a g produced which can be conveniently ca, handled. The side plates of the casing carry the shafts l on which the roller bodies 5 ro- In the roller bodies 5 which consist of rubber, caoutchouc or the like resilient material. cavities 6 are provided which form the suction cups, by means of which the portions of the washing situated directly thereunder are ijected to a suction effect. To increase the cleaning effect of the suction cups warts i' may be provided on the roller beside the cups, which warts press down the washing, that more the same against the suction effect. ig. 3 cavities 10 may be As shown in I provided in the roller, which may be made of fine material into which cavities special socket 11 are inserted, which form between their bea ded border 13 the suction cup 12. In this case the roller 5 needs not to consist of resilient material but can be made or wood, metal or the like. This last construction presents the advantage that the individual suction cups can be replaced without it bcin g necessary to change the entire roller body.

When using the washing apparatus according to the invention the suction cups yielding on their foot to lateral pressure are pressed hat individually against the washing and, when the pressure is removed, suck the lye through the material owing to resuming their initial shape. Consequently the fibres of the material will be subjected to the greatest possible cleansing effect of the lye.

I claim:

A washing apparatus, comprising a pair of rollers each provided with a plurality of sockets, each of said sockets extending inwardly from the surface of the roller towards the central axis thereof and having its cross sectional area progressively increasing inwardly, and a plurality of resilient suction cups each having a shank embedded in a socket.

In testimony whereof I have signed my name to this specification.
